Museum Ship Maintenance via 3D Printing

USS Massachusetts (BB-59), the third of four SoDak super dreadnoughts built during WWII, turned 80 this year.

Of course, she only spent five of those years on active duty (earning 11 Battle Stars fighting the Vichy French and Japanese) and another 15 years in mothballs before shuffling to Fall River, Massachusetts in 1965 to assume an enduring auxiliary role as a museum ship.

Using donations and support from the Commonwealth, “Big Mamie” has been getting a lot of work done including “prepping, priming, and painting the main deck waterways, a complete hull repainting to include all numbers and her name, and welding work to repair main deck stanchions,” while her “her main deck fantail and 40mm gun tubs aft are being completely prepped, primed, and painted as well.”

Museum staff are also taking advantage of a new 3D printing lab aboard the vessel to craft new parts to replace those that have long ago broken or walked off with visitors over the years.

Now that is beautiful.

Meet the all 3-D printed Wave suppressor

One of the more interesting cans I saw at the American Suppressor Association media day event at the Griffin Gun Club was the DD Wave, named such in recognition of its cascading “wave” pattern baffle geometry.

The WAVE uses Inconel, a nickel-chromium-based superalloy, with stainless steel and titanium to produce a 7.6-inch can that is crafted completely through direct metal laser sintering (DMLS) additive manufacturing. The method negates the traditional tube and baffle system used by legacy platforms. The suppressor base is the serialized part, meaning the main body of the WAVE can be sent in for service if needed without an NFA hassle.

One 3-D printer away…

I’ve been covering the story of a DIY gun maker who goes by derwoodvw, a 47-year-old carpenter, and his very AR-ish/Tec-9 looking Shuty MP 1 semi-auto pistol made almost completely of plastic for a minute over at Guns.com.

His latest version uses an aftermarket Glock 17 barrel along with a 3D printed lower and upper designed to use G17 mags. He says he has gotten 3K rounds out of it without jamming thus far.

A big step from the homemade guns of yesteryear. You can almost picture resistance armorers in occupied wherever peering at their desktop 3D printer in the dim lights of their basement workshops, the hand-rolled cigarette of the 1940s replaced with a vape…
